lTo all 'whom 'it lmay concern: y f Be it known thatI, Riel-IanniDoxovAN, l of Ambridge, Beaver county, lennsvlvania, have invented anew' andl'usel'ul `Barge, of l `which the following is a full, clear,and exaccompanying drawmgs,forming part of this Specification, inWhichuFigure 1 is a side elevation showing the end 'portion of a .woodenbarge constructed partial ligitudinal section, and Fig. 3 a top planView.'` I ,l My linvention relates to the class of wood in' barges, andis designed to provide at each end, these compartments being ofsutiicient capacity to float the barge in ease of accident, and prevent.the sinking thereof.

In the draivings, 2, 2 represent the wooden side planking Vof the bargecomposed of planks, which are secured at their ,front ends to thevertically inclined interior timbers The front end portionsV of theseplanks are covered by the steel sheathing or side plating 4, and theplanks and plating are secured by- .bolts 5 extending through thetinibers'-l and having countersnnk heads Within the side plating 4. Theentire end portion of the barge is preferably made. of steel .platesforming the side plating and the rake platng,'tl1ese being joined at thecorner by any suitable corner plates or corner pieces, the sheathing soformed being filled over the wooden body of the barge ut each end.

At. each end of the, barge within themetal sheathings. I provide anairtight compart-4 ment formed vby the steel rake bottom plating 8, thesteel rake side plating 4, the steel end bulk-head 7, and thesteelhandling deck 9, withv suitable interior bracingf. The

-by atransverse channel mem 'i'iialteithfm water-tight and they may beprovided with an air-tight entrance hatch, it' desired. A

1.0 designates the bmn'pin block formed iierto which the rake plating isfastened, and suitably reinforced by gusset plates 1l.

'The advantages of my invention result from the providing of the woodenbarge with steel ends; and particularly from the use of the endwater-tight-compartments. By making these. compartments of sutlicientsize, they will tloat. the barge so if itI is sunk it may be raised bymerely removing the lading. On taking out. the lading the watertightcompartments will cause the barge to floatto the surface.

Many changes may be made in the tormand ar angement of the training, the'form and size of the water-tight compartments, &c., without departingfrom my invent-ion,

I claim y l. A Wooden barge having a. steel rake end, consisting ofsideplating, bottom plating curved upwardly to form the rake, head orbumping block, a steel handling deelt, and

a steel water-tight bulk head; substantially as described.

2. A wooden barge having a steel rake end; consisting of side plating',bottom plat .ing curved in )wardlyto form the rake. head or bumpingblock, a steel handling deelt and 4'a .steel water-tight bulk head, saidend conw taining a water-tight compartme `t to therelby give sufficientbnoyancy'to tioat the barge; substantially as described.l

ln testnnony whereof, l have hereunto set my hand.
